We look at the division of 7751470 by 661 
Let's see how many times 661 fits into 7751470.

Step 1:
661 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 661

Step 2:
661 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 661

Going ahead to step 3:
661 goes into 775 1 times with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 661 away from 775, we end up with 114.
Append the next digit (1) from the dividend to 114 and continue with: 1141 / 661

On to step 4:
661 can be fit into 1141 1 times, resulting in a remainder of 480.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 661 from 1141 and we're left with 480.
Bring next digit (4) of the dividend behind the 480 and repeat the process: 4804 / 661

Moving on to step 5:
4804 divided by 661 is 7 with a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 4627 from 4804, we get 177.
Bring next digit (7) of the dividend behind the 177 and repeat the process: 1777 / 661

Going ahead to step 6:
661 goes into 1777 2 times with a remainder of 455.
Use 2 as the next digit of our solution. 
Result so far: 1172.0
If we subtract 1322 from 1777, we get 455.
Grab the next digit (0) from the dividend, add it to 455, then carry on: 4550 / 661

Going ahead to step 7:
661 can be fit into 4550 6 times, resulting in a remainder of 584.
Use 6 as the next digit of our solution. 
Result so far: 11726.0
Subtracting 3966 from 4550 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 8:
661 goes into 5840 8 times with a remainder of 552.
The number 8 becomes the next digit in our result. 
Result so far: 11726.8
Subtracting 5288 from 5840 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 9:
When dividing 5520 by 661, we get 8 with a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 11726.88
Deduct 5288 from 5520 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 11726.88, and the remainder is 0.232.
